No. 7,963,575 relates to a gate latch assembly comprising a biased latchbolt movable between a retracted position and an extended position and a latchbolt catch to selectively receive the latchbolt. A two-stage mechanism for repositioning the latchbolt from the extended position to the retracted position, including a first stage mechanism having a clutch to selectively engage the latchbolt and a second stage mechanism for repositioning the latchbolt from the extended position to the retracted position while the clutch is engaged where the second stage mechanism is repositionable independent of the latchbolt when the clutch is not engaged.
- U.S. 2011/0148126 discloses a latch for securing a gate closed comprising a bar assembly disposed on the gate. The bar assembly comprises a bar member which is attractable by a magnet. An engagement assembly is disposed on the fence to engage the bar member. An elongate member movable between an attraction position in which attraction between a magnet and the bar member causes movement of the bar member into engagement with an engagement assembly when the gate is closed and a release position in which attraction between the magnet and the bar member is reduced, enabling disengagement of the bar member from the engagement assembly.
- U.S. Pat. No. 5,362,116 shows a self latching device to latch in two members which are otherwise movable relative to each other for use with a gate. The device comprises a latch arm mounted to one of the members movable between a latched position and a retracted position, and a retaining element with a permanent magnet mounted to the other member. The latch arm is normally spring biased in the retracted position but is moved by the magnetic field generated by the magnet to the latched position to secure the gate in a closed position.
- U.S. Pat. No. 5,664,769 teaches a gate assembly for tensioned fences such as used to enclose the perimeter of home swimming pools. The gate in a preferred form is “U” shaped with no rigid bar at the top has the space between the bars of the gate filled with tensioned mesh fabric similar to the tensioned fence. The gate is supported by poles on each edge which provides spring closed hinging on one edge and an automatic latch at the opposite edge. The poles are pairs of poles at each side which together react to the tension of the fence without transferring the fence tension to the gate.
- U.S. Pat. No. 7,044,511 relates to a magnetic latch system including a latch assembly and a keeper assembly. The keeper assembly includes a magnetically attractable keeper pin. The latch assembly includes a magnet and a movable internal lever to engage the keeper pin to move it away from the permanent magnet. The system may also include a lock to hold the internal lever in a fixed position so that it cannot be moved to move the keeper pin away from the magnet.

latch assembly 12 and thekeeper assembly 14 are attached to the fence post (not shown) adjacent the fence opening (not shown) and the gate (not shown) respectively in proper vertical alignment relative to each other. - The lower latch pin or
member 44 is normally biased in upper or unlocked position by the bias orcompression spring 46 acting on or engaging the upper bias latch pin stop 48 to engage the substantially horizontalupper limit member 60 of thelatch pin limit 58 and thebias support shoulder 55. - Since the
magnet 80 is disposed adjacent the latch pin recess orlatch pin receptacle 76, when the gate (not shown) is closed, the lower latch pin ormember 44 and upperlatch actuator assembly 16 are moved from the normally biased upper or unlatched position to the lower or latched position as the latch pin ormember 44 is drawn or pulled into the latch pin recess orreceptacle 76 against the force of the bias orcompression spring 46 by the force of themagnet 80. - To release the
keeper assembly 14 to open the gate (not shown), the upperlatch pin actuator 16 and the substantially ridged elongated latch pin actuator bar ormember 28 is pulled upwardly withdrawing the lower latch pin ormember 44 coupled to the lower latchpin actuator support 30 from the latch pin receptacle orrecess 78 as the bias orcompression spring 46 moves the lower latch pin ormember 44 to the upper or unlocked position when the lower latch pin ormember 44 is no longer within the magnetic field of themagnet 80. - When the gate (not shown) is closed, the
keeper assembly 14 is normally held in the closed position by the lower latch pin ormember 44 of the lowerlatch pin assembly 18 disposed within the latch pin receptacle orlatch pin recess 78 of thekeeper assembly 14 by the magnet 82. In addition, thelatch assembly 12 may be locked against vertical movement by thelock assembly 34. - However, as shown in
FIGS. 3 and 7 , if sufficient downward force is applied to the gate (not shown) such as a child attempting to swing on the gate, thelatch assembly 12 and thekeeper assembly 14 may become misaligned relative to each other in the horizontal plane as depicted by the phantom lines. To prevent the gate (not shown) from opening, the substantially vertical catch or stopsurface 66 of the upwardly projectingstop member 62 of thekeeper safety catch 20 engages thelower portion 84 of therear wall 86 to limit the horizontal outward movement of thekeeper assembly 14 relative to thelatch assembly 12 to prevent the lower latch pin ormember 44 from becoming dislodged from thelatch pin recess 76 to maintain the gate (not shown) in the latched or closed position. Therear wall 86 is shorter than thefront wall 88 forming a notch or opening 90 allowing thekeeper assembly 16 to close without engaging thekeeper safety catch 20 of thelatch arm 74 of thekeeper assembly 14. - It will thus be seen that the objects set forth above, among those made apparent from the preceding description are efficiently attained and since certain changes may be made in the above construction without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
- It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
- Now that the invention has been described,
